Reports: Celtics' Leandro Barbosa suffers season-ending knee injury

ESPN.com and CSNNE.com reported Tuesday that Barbosa tore the ACL in his left knee during the third quarter of a 94-91 loss to the Bobcats in Charlotte on Monday night.

With less than one minute to play in the third quarter and the Bobcats leading 75-70, Barbosa came up limping on a drive to the baseline. Replays showed no contact on the play; his left leg simply appeared to buckle and give way. He was unable to get back on defense and he was eventually carried off the court by his teammates. He did not return. The Celtics announced after the game that Barbosa would undergo an MRI on Tuesday.

"Thank you all for your messages and support," Barbosa tweeted on Tuesday. "It means a lot."
